ALEXANDER T. BRANN AND AUGUSTUS TV. 'BRANN, OF DAYTON, NEVADA.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 433,558, dated August 5, 1890" Application filed September 1'7; 1889. Serial No. 324,227. (No model.)

To aZZ whom it may concern:

Beit known that we, ALEXANDER T. BRANN and AUGUSTUS W. BRANN, both citizens of the United States, and residents of Dayton, in the county of Lyon and State of Nevada, have jointly invented a new and useful CarriagelVrench, of which the following is aspecification.

Our invention relates to improvements in that class of nut-wrenches for vehicles which are employed to fasten and unfasten the nut which secures the hub of the wheel to the spindle of the axle of the vehicle, and which is constructed so as to be turned with the wheel to work the nut onto or off of the screwthreaded end of the axle-spindle.

The invention has for its objects to provide a light and substantial wrench that may be readily applied to the nut at the end of the spindle and connected to one of the spokes of the wheel in such manner as to be moved therewith and without defacing or injuring the spoke or the surface-coating of varnish thereon, as more fully hereinafter set forth.

In the accompanying drawings, forming part of this specification, Figure 1 represents a perspective view of our improved wrench, and Fig. 2 represents a perspective view showing a portion of a vehicle-wheel with the wrench in position for use.

Referring to the drawings, the letter A in dicates the jaw or recessed portion of the wrench, which is designed to fit over and seize the nut at the end of the axle'spindle. The said jaw is preferably rectangular in shape, to fit a rectangular nut; but it is evident that it may be made polygonal to fit nuts of polyg onal shapes. From the said jaw extends the arm or lever of the wrench, which is curved as shown at B, and then laterally extended as indicated by the letter O, the extremity of the lateral extension C being bent at substantially a right angle, and the bent portion having formed in it a V-shaped recess E, which will fit over one of the spokes of the wheel when the wrench is applied.

The recess in the bent portion of the arm of the wrench is so formed that the members at each side thereof, when brought to bear upon the spoke, set againstit slightly, merely hearing against it with sufficient force to hold the arm in contact with the spoke, without sufficient pressure to effect any abrasion or injury to the spoke. The letter F indicates a link, having an eye at one end adapted to slide over the arm of the wrench, and a hook at its free end which can be made to engage any particular spoke of the wheel when the wrench is applied, and bind the angular recessed extremity of the wrench to the spoke in such manner as to fasten it securely thereto with-- out injuring the same, It is our intention to cover or coat the angular recess E of the upper end of the extension 0 and the hooked end of the link F with rubber, to further guard against abrasion of the varnished spokes.

From the above description it will be seen that our improved wrench may be constructed of a single piece of metal, without adjustingscrews or other adjuncts to fit it in place upon the nut and wheel of the vehicle, and that by means of the link F the arm of the wrench may be lightly clamped to one of the spokes of the wheel. in such manner as to be carried with it, while at the same time it will hear so lightly against the spoke as to leave even its surface coating of varnish free from injury or abrasion.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

1. A nut-wrench for vehicles, having a jaw to encompass the nut at the end of the axlespindle, a lateral arm bent so as to extend over the edge of the hub, and a laterally-bent and recessed extremity to fit one of the spokes of the wheel, so as to be turned with the wheel to operate the wrench, substantially as specifled.

2. In combination with a nut-wrench for vehicles, having a jaw to seize the nut on the axle-shaft, a lateral arm with an an gularly-recessed extremity to bear against one of the spokes 0f the wheel of a vehicle, of a link loosely located on the lateral arm of the wrench, and provided with a hook at its free end whereby the arm of the wrench may be temporarily bound to the spoke of the wheel, so as to move therewith and without defacing the same, substantially as specified.
